Jenna Elfman, Amy Smart on pilot duty

Actresses land lead roles in CBS, ABC projects

Jenna Elfman and Amy Smart have been tapped as the leads of CBS' comedy pilot "Accidentally on Purpose" and ABC's drama pilot "See Cate Run," respectively.

The casting of Elfman lifts the contingency on "Accidentally."

The project, from CBS Par and BermanBraun, revolves around Billie (Elfman), a San Francisco movie critic who finds herself "accidentally" pregnant after a fling with a younger man, and the unconventional family that comes from this "mistake."
